Overview

The Hurco TMX8i is the performance-oriented version of Hurco's 8-inch chuck turning center, designed for shops that need more spindle power, rigidity, and turning envelope than the standard TM8i. The TMX designation signals a step up in construction and capability — heavier castings, more powerful spindle, and the capacity to handle tougher materials and larger workpieces consistently.

The main spindle delivers 27.8 kW (37.3 hp) at up to 4,500 RPM with 239 Nm (176.3 ft-lbs) of torque. That's double the power of the TM8i (18 hp), which makes a real difference on heavier cuts in stainless, 4140, and other alloy steels. The A2-6 spindle nose accepts an 8-inch hydraulic chuck, and the 51 mm (2.0 in) through-spindle bore matches the TM8i for bar feeding capability.

Maximum turning diameter is 336 mm (13.2 in) with a swing over bed of 560 mm (22 in) and a maximum turning length of 530 mm (20.9 in). Travels are 286 mm (11.3 in) in X and 560 mm (22 in) in Z, with rapid traverse at 24 m/min on both axes. The 12-station servo turret uses the Duplomatic fast-indexing design for quick tool changes.

Construction features Meehanite cast iron with precision linear ball rails and pre-tensioned double-nut ball screws. At approximately 4,125 kg (9,095 lb), the TMX8i weighs significantly more than the TM8i, providing noticeably better vibration damping during heavy turning. The machine includes a spindle chiller to maintain thermal stability during extended production runs.

The TMX8i shares its platform with the TMX8MYi mill-turn machine — if you need Y-axis and live tooling later, the TMX platform is the foundation. For shops that don't need live tooling but want production-grade turning performance with WinMax conversational programming, the TMX8i is the right choice. It competes with the Haas ST-20, Doosan Lynx 2100B, and Okuma LB2000 EX III.

Strengths & Limitations

Strengths

37.3 hp spindle with 239 Nm torque delivers production-grade cutting performance in steel and stainless without compromise
Heavier construction at 4,125 kg provides superior vibration damping compared to lighter-duty 8-inch lathes in this class
WinMax conversational control maintains Hurco's programming speed advantage on a performance-oriented platform
Shares platform with TMX8MYi, so shops familiar with the TMX can transition between 2-axis and mill-turn easily
Spindle chiller maintains thermal stability during extended production runs and tight-tolerance work
286 mm X-travel is generous for an 8-inch chuck lathe, providing clearance for larger tooling setups

Limitations

No live tooling on the TMX8i — milling and cross-drilling require the TMX8MYi or a secondary VMC operation
Higher price than the TM8i may not be justified if most work doesn't require the extra spindle power
51 mm bar capacity is the same as the TM8i — no bar feeding advantage despite the performance upgrade
4,500 RPM max spindle speed matches the TM8i and lags behind some competitors at 5,000-6,000 RPM
Hurco dealer network remains smaller than Haas or Mazak for parts and service support

Best For

Job shops running heavier cuts in stainless, alloy steels, and cast iron that overwhelm the standard TM8i Production turning cells where the 37.3 hp spindle reduces cycle times on material-intensive parts Shops planning to eventually add a TMX8MYi mill-turn and wanting operators trained on the TMX platform Aerospace subcontractors turning parts in Inconel, titanium, and high-strength alloys that demand spindle power High-mix shops that need production-grade performance with conversational programming flexibility Shops replacing older manual or early CNC lathes that want a significant performance upgrade

Frequently Asked Questions

01 What is the difference between the TMX8i and TM8i?

The TMX8i delivers 37.3 hp vs 18 hp on the TM8i, with 239 Nm of torque vs roughly half that. The TMX8i also has heavier construction (4,125 kg vs 3,400 kg), longer turning length (530 mm vs 455 mm), and more X-axis travel (286 mm vs 200 mm). The TMX8i is built for heavier cuts and production work; the TM8i is for lighter-duty job shop turning.

02 What does a Hurco TMX8i cost?

A new Hurco TMX8i typically sells between $95,000 and $135,000 depending on options including tailstock, chip conveyor, and tooling. Used TMX8i machines trade between $50,000 and $85,000 depending on year, hours, and condition.

03 How does the TMX8i compare to the Haas ST-20?

The Haas ST-20 offers similar turning capacity at a lower base price with better dealer coverage. The TMX8i counters with WinMax conversational programming and slightly better build quality with the spindle chiller and heavier casting design. For shops that prioritize programming flexibility, the Hurco premium pays off in reduced setup time.

04 Can I upgrade the TMX8i to add live tooling?

No. The TMX8i is a dedicated 2-axis turning center. Live tooling and Y-axis capability require the TMX8MYi, which is a separate machine built on the same TMX platform. If there's any chance you'll need mill-turn capability, consider starting with the TMX8MYi.

05 Is the TMX8i suitable for hard turning?

The TMX8i can perform light hard turning on case-hardened parts (typically HRC 55-62) with CBN inserts. The rigid construction and 37.3 hp spindle support it, but it's not a dedicated hard turning machine. For consistent hard turning, you'd want a machine specifically designed for that application.
